A Case Study of Subsidence over an Abandoned Underground Limestone Mine…

The surface damage due to subsidence is an inevitable consequence of underground mining, which may be immediate or delayed for many years. The surface damage in an abandoned underground limestone mine in Korea is observed to be of different forms from simple sinkhole formation to a large scale landslide of the ground in the subsided area.
